10 个用于收集硬件信息的 Linux 命令

2021-02-16    分类: 网站建设

1.如何查看Linux系统的信息

如果只想知道系统名称,可以使用不带任何参数选项的uname命令,就可以输出系统信息,或使用uname -s命令输出系统的内核名称。

tecmint@tecmint ~ $ uname
Linux

要查看网络主机名,用“-n”参数选项的uname命令,如下所示。

tecmint@tecmint ~ $ uname -n
tecmint.com

要获取有关内核版本的信息,使用“-v”参数选项。

tecmint@tecmint ~ $ uname -v
#64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014

要得到有关你的内核的发行版信息,请使用“-r”参数选项。

tecmint@tecmint ~ $ uname -r
3.13.0-37-generic

要输出你的机器的硬件名,使用“-m”参数选项:

tecmint@tecmint ~ $ uname -m
x86_64

所有这些信息可以通过运行“uname -a”命令,如下图所示一次性输出。

tecmint@tecmint ~ $ uname -a
Linux tecmint.com 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2.如何查看Linux的系统硬件信息

你可以使用lshw工具来收集有关硬件部件,如CPU,硬盘,内存,USB控制器等的大量信息。

lshw是一个相对比较小巧的工具,当你提取信息的时候,只有为数不多的几个选项可供你使用。由lshw提供的信息收集形成了不同的/ proc文件。

注:请记住,lshw命令是由superuser (root)或sudo用户执行的。

参见:《Difference Between su and sudo User in Linux》

要输出你的Linux系统的硬件信息,运行此命令。

tecmint@tecmint ~ $ sudo lshw

......

你可以通过使用-short选项来输出汇总的硬件信息。

tecmint@tecmint ~ $ sudo lshw -short

如果你想生成输出为HTML文件,可以使用选项-html。

tecmint@tecmint ~ $ sudo lshw -html > lshw.html

3.如何查看Linux的CPU信息

要查看关于CPU的信息,就使用lscpu命令,因为它能从sysfs和/ proc / cpuinfo中显示CPU体系结构的信息,例如CPU数字,核心,CPU系列型号,CPU高速缓存,线程等。

tecmint@tecmint ~ $ lscpu

4.如何收集Linux块设备信息

块设备是诸如硬盘,闪存驱动器等的存储设备。lsblk命令可用于报告有关块设备的信息,如下所示。

tecmint@tecmint ~ $ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk 
├─sda1 8:1 0 1000M 0 part

└─sda10 8:10 0 7.9G 0 part [SWAP]
sr0 11:0 1 1024M 0 rom

如果你想查看系统上所有的块设备,那么就加一个-a选项。

tecmint@tecmint ~ $ lsblk -a
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 931.5G 0 disk 
├─sda1 8:1 0 1000M 0 part

5.如何输出USB控制器的信息

lsusb命令可用于报告关于USB控制器和所有连接到它们的设备的信息。

tecmint@tecmint ~ $ lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

你可以使用-v选项生成有关于每个USB设备的详细信息。

tecmint@tecmint ~ $ lsusb -v

6.如何输出PCI设备信息

PCI设备可能包括USB接口,显卡,网卡等。lspci工具能用来生成系统上所有PCI控制器以及连接到它们的设备的信息。

要输出有关PCI设备的信息,可运行以下命令。

tecmint@tecmint ~ $ lspci
00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

03:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev a2)

使用-t选项将以树的形式生成输出。

tecmint@tecmint ~ $ lspci -t
-[0000:00]-+-00.0
 +-02.0
 +-03.0
 +-14.0

 +-1c.3-[02]----00.0
 +-1c.4-[03]----00.0
 +-1d.0
 +-1f.0
 +-1f.2
 \-1f.3

使用-v选项生成有关每个连接的设备的详细信息。

tecmint@tecmint ~ $ lspci -v

7.如何输出SCSI设备的信息

要查看所有的scsi / sata设备,可使用lsscsi命令,如下所示。如果你没有安装lsscsi工具,那么运行下面的命令来安装它。

$ sudo apt-get install lsscsi [on Debian derivatives]
# yum install lsscsi [On RedHat based systems]
# dnf install lsscsi [On Fedora 21+ Onwards]

安装后,运行lsscsi命令,如下所示:

tecmint@tecmint ~ $ lsscsi
[0:0:0:0] disk ATA ST1000LM024 HN-M 2BA3 /dev/sda 
[1:0:0:0] cd/dvd PLDS DVD-RW DA8A5SH RL61 /dev/sr0 
[4:0:0:0] disk Generic- xD/SD/M.S. 1.00 /dev/sdb

使用-s选项来显示设备尺寸。

tecmint@tecmint ~ $ lsscsi -s
[0:0:0:0] disk ATA ST1000LM024 HN-M 2BA3 /dev/sda 1.00TB
[1:0:0:0] cd/dvd PLDS DVD-RW DA8A5SH RL61 /dev/sr0 -
[4:0:0:0] disk Generic- xD/SD/M.S. 1.00 /dev/sdb -

8.如何打印有关SATA设备的信息

你可以使用hdparm实用工具在系统上找到有关sata设备的一些信息,如下所示。在下面的例子中,我使用了块设备/ dev / sda1。

tecmint@tecmint ~ $ sudo hdparm /dev/sda1
/dev/sda1:
 multcount = 0 (off)
 IO_support = 1 (32-bit)
 readonly = 0 (off)
 readahead = 256 (on)
 geometry = 56065/255/63, sectors = 2048000, start = 2048

要输出设备有关柱面、磁头、扇区、大小和起始偏移量的几何信息,使用-g选项。

tecmint@tecmint ~ $ sudo hdparm -g /dev/sda1
/dev/sda1:
 geometry = 56065/255/63, sectors = 2048000, start = 2048

9.如何输出Linux文件系统信息

为了收集有关文件系统分区的信息,你可以使用fdisk命令。虽然fdisk命令的主要功能是修改文件系统分区,但我们也可以用它来查看文件系统上不同分区的信息。

你可以按如下方法输出分区信息。记住要用超级用户的身份运行命令,否则你可能看不到任何输出。

tecmint@tecmint ~ $ sudo fdisk -l
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

10.如何提取有关硬件组件的信息

你也可以使用dmidecode实用程序通过读取DMI表中的数据提取硬件信息。

输出有关内存的信息,作为超级用户运行此命令。

tecmint@tecmint ~ $ sudo dmidecode -t memory
# dmidecode 2.12
